In all honesty, I haven't had a cavity in something like 15 years?
Same deal with the braces gig, I still have my fangs but the two teeth outside of them got yanked. To me, it still seems like it was a waste.
The Navy yanked my lower wisdom teeth mainly because I got my orders changed to the Barbel in Japan. That was where I probably got into the most trouble, Barbel was all about really serious fresh water restrictions and we'd wait until the galley served soup to brush our teeth.
The chomper that got yanked today was always on the back burner. My Dentists always told me they'd deal with it when the time was right.
The last wisdom tooth has always acted like it was in the witness protection program and its always kept a low profile. We checked it in the last set of X Rays and it hasn't done much of anything. The problem with digging it out is that it would require some serious oral surgery because its buried deep.
